PRINTERS CHASE.

SPECIFICATION formingpart of Letters Patent No. 715,685, dated December9, 1902.

Application filed August 17, 1901. Serial No. 72,413. (No model.)

To a whom it may concern.-

Be it known that I, FRANK A. MCGUIRE, a citizen of the United States,residing at Jackson, in the county of Cape Girardeau and State ofMissouri, have invented new and useful Improvements in Printers Chases,of which the following is a specification.

This invention relates to printers chases, the object in view being toprovide a chase having complete form-locking means in itself, thus doingaway with the necessity of employing shooting-sticks, quoins, furniture,and mallets.

A further and very important object of the present invention is to soarrange the locking devices that they will not necessitate enlarging theside and end portions of the chase, which would result in taking upvaluable space and materially reducing the size of the form included inthe chase.

Another object of the invention is to form the side and end bars of thechase in such manner as to facilitate the manipulation of the lockingdevice.

With the above and other objects in view the invention consists in thenovel construction, combination, and arrangement of parts hereinafterfully described, illustrated, and claimed.

In the accompanying drawing, the figure represents a perspective view ofa printers chase constructed in accordance with the present invention.

In carrying out my invention I construct the chase in rectangular formand provide the four corners thereof with squared reinforce blocks 7,and integral therewith is formed the side and end walls 1 and 2, and tothe lower edges of the side and end walls and between the fourreinforce-blocks I secure the supporting-ledges 3, having their frontedge portions extending to the front faces of said blocks in the sameplane with each other.

The numeral 9 indicates the longitudinal slotted bars, and 10 thetransverse slotted bars, having bearings at their outer ends which areadapted to be loosely mounted on the supporting-ledges 3, so as toextend to the outer edge portions thereof. 'Each of these longitudinaland transverse bars are slotted to their bearing ends, and each of saidbars are loosely connected together one Within the other by theinterlocking of the slotted portions thereof, which renders them capableof having a movement to or from each other, as shown in the drawing. Thebearing ends of the longitudinal and transverse bars have movablymounted in openings therein clamping screw-rods 4, the opposite outerends of which are journaled in the reinforce-block 7. To the centralportions of the clamping screw-rods I secure sleeves 5, having openings6 in their peripheries arranged at suitable distances apart therein. Infront of each sleeve and in the upper edges of the side and end walls Iform recesses 8 of a length equal to that of said sleeves.

'When it is necessary to move the longitudinal and transverse barstoward each other for the purpose of locking the form in the slottedbars, the same is accomplished by means of inserting a pointed implementin the openings of the sleeves and by turning the implement downward inthe recesses causing the journal ends of the clamping-rods to turn inthe reinforce-blocks, which permits of the turning of said clamping-rodsin the bearing ends of the slotted bars, whereby the bottom edgesurfaces of said bearings have a lateral sliding movement on thesupportingledges, thereby moving the slotted bars toward each other.

I attach importance to the construction of the supporting-ledges inconnection with the bearing ends of the slotted bars mounted looselythereon, whereby said bearing ends are permitted to have a lateralsliding movement on the supporting-ledges. I also attach importance tosaid ledges, as they support the slotted bars and relieve the strainthereon when the form is incased between the same. I further attachimportance to the recesses which are located in the upper portions ofthe side and end walls of the structure whereby to coact with thesleeves, so as to give the clamping-rods more of a turn in their journalends.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is

A printers chase consisting of a rectangular frame provided withreinforce-blocks in each corner thereof and having side and end wallsformed therewith, the supporting-ledges secured in the same plane witheach other, to the lower edges of the side and end walls and between thereinforced blocks, the longitudinal and transverse slotted interlockingbars having bearing ends loosely mounted on the ledges, theclamping-rods passing through openings in the bearing ends of theslotted bars and havingtheir opposite ends journaled in thecorner-blocks, sleeves on said clamping-rods, and recesses in the upperportions of the said side and end walls arranged in front of the sleevesso as to ooact therewith, whereby the bearing ends of said bars areadapted to have a lateral sliding movement on the saidsupporting-ledges, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK A. MCGUIRE.
